VAGINAL SYRINGE.

Specification of Letters Patent.

Application filed September 22, 1909. Serial No. 518,902.

T o all whom it may concern:

Be it known that I, OSCAR KATZENBERGER, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a new and I1nproved Vaginal Syringe, of which thefollowing is a full, clear, and exact description.

The invention relates to vaginal syringes, such, for instance, as shownand described in the Letters Patent of the United States, No. 903,098,granted to me on November 3, 1908. p

The object of the invention is to provide a new and improved vaginalsyringe, more especially designed for spraying medicinal powders ontodiseased parts of the vagina, and arranged to permit convenientlycharging the powder container` of the syringe with powder, to insure aproper spraying and spreading of the powder and to provide an escape for'the air pressure from the vagina.

For the purpose mentioned, the syringe is provided with a powdercontainer on the discharge end of a compressible bulb, and a vaginalnozzle is connected with the said container so that on pressing the bulbthe air therein is compressed and forces the powder' out of thecontainer and through the nozzle to the afflicted part.

A practical embodiment of the invention is represented in theaccompanying drawingsforming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a partly sectional side elevation of the syringe on the line1-1 of Fig. 2; Fig. 2 is a plan view of the saine; Fig. 3 is a sideelevation of the combined powder container and nozzle; and Fig. 4 is anenlarged inverted plan view of the powder container.

In the neck A of the bulb A of the syringe is fitted the powdercontainer B, on which is screwed or otherwise secured the nozzle C, thesaid bulb A being preferably made of soft rubber or other elasticmaterial, while the container B and the nozzle C are preferably of hardrubber. The powder container B is provided with a central bore B',opening at its lower end into the bulb A, and provided with a perforatebottom B2 for supporting the medicinal powder to be sprayed and forallowing compressed air from the bulb A to pass to the powder and forcethe same out of the container B and nozzle to the aliiicted part of thevagina.

The nozzle C is provided with a conical head C', terminating at its apexin the nipple C2, and the nozzle C is also provided with a central boreC3, the inner cylindrical portion of which is in register with the boreB of the powder container B. The outlet of the bore C3 is in the form oftwo cones C4, C5, having adjacent apexes, as plainly indicated in Fig. lso that the medicinal powder forced from the bore B through the bore C3by the air blast from the bulb A is concentrated by the inner cone C5and spread or scattered forcibly by the outer cone C4, to reach allafliicted parts. The head C of the nozzle C serves to close the entranceof the vagina and prevents the nipple C2 from passing too far into thevagina, and the said head C and nipple C2 are provided with externallengthwise-extending grooves C, to allow escape of the compressed orexcess air passing into the vagina with the medicinal powder whenpressing the air bulb A.

In using the syringe, the nozzle C is unscrewed from the powdercontainer B, and then the charge of medicinal powder is filled into thecontainer, after which the nozzle C is again screwed onto the container.The nipple C2 is now passed into the vagina with the head C wedged intothe entrance of the vagina. The user now presses the bulb A, so that themedicinal powder is ejected from the outlet of the nipple in the form ofa spray and with more or less force according to the pressure applied.

The syringe shown and described is exceedingly simple and durable inconstruction and cheap to manufacture, being composed of but threeparts, not liable easily to get out of order or clogged up, as theperfor-ations in the bottom B2 are kept clean by the air blast and but asingle bore is provided in the nozzle C.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. A vaginal syringe for spraying medical powderscomprising a compressible bulb and a perforated powder container havingone end secured to the said bulb and the other end removably attached toan externally grooved nozzle, provided with a conical externally-groovedhood and having a bore, the inlet portion of which is cylindrical andthe outlet portion of which is in the form of a double cone havingadjacent apexes.

Patented Feb. 15, 1910.

2. A vaginal syringe for spraying niedicinal powders, provided with anozzle having a nipple and a conical head, the said nipple and headhaving external grooves for the escape of air from the vagina on usingthe syringe and the said nipple having` an outlet of double cone shape.

3. A vaginal syringe for spraying` inedicinal powders, comprising abulb, a powder container attached to the neck of the said bulb andprovided with a perforated bottoni, and a nozzle screwing` on the saidpowder container and having a bore, the inner inlet portion of which iscylindrical and thel outlet in the forni of a double cone havingadjacent apexes.

4. A vaginal syringe for spraying rnedicinal powders, comprising a bulb,a powder container attached to the neck of the said bulb and providedwith a perforated bottoni, and a nozzle screwing on the said powdercontainer and having a bore, the inner inlet portion of which iscylindrical and the outlet portion in the forni of a double cone havingadjacent apeXes, the nozzle having a nipple and a conical head, the saidnipple and head having external grooves.

In testimony whereof I have signed iny naine to this specication in thepresence of two subscribing witnesses.
